It looks like the folks over at CloudLinux are looking to shake up the rebootless kernel update market with their introduction of KernelCare (http://kernelcare.com/).  They announced pricing on March 30th, with retail sales starting on the 1st, so it's a newer solution, but looks promising.

They support CentOS6, RHEL6, CloudLinux 6, OpenVZ for x86_64 unmodified kernels currently, with more coming down the road.

Anyone give this a shot yet, and if so how has it been working for you?

KGraft is an open source and *free* alternative to KSplice and KernelCare, it was released to the public about 3 weeks ago.

Edit: There is also one called KPatch, these tools are less automated than KernelCare, but in that you will have more control over the patching process. 

----

One thing to note about procedurally updating the kernel this way is the kernel may not have issues while your server is running, but if the server gets rebooted a patch may cause some unforeseen issue and the server may not boot properly. I've seen mentions of this as a potential pitfall for tools such as this.

I've been a ksplice customer since 2010 or so, sticking with that as it's cheap & proven to work.

Well, redhat does support this for I don't know how long (at least 3 years?). But it's quite nice that they're applying it to other distros.

Ksplice offers only services to oracle linux I think now, so thank you for the share, will give kernelcare a try.
